Parts for Ge CVM1790SS4SS: Control Parts

Self-tapping pan-head screw secures interior panels, vent grills, and brackets in microwaves. Replace missing, stripped, or lost screws during repairs.

Fix a microwave that won't heat, start, or respond to controls with a new main control board. This repair requires moderate skill and basic tools.

This control knob restores tactile control to your appliance's front panel so you can select settings easily and safely. It replaces a cracked, worn or missing knob to make range or oven adjustments simple again. What it does:

• Replaces a damaged or missing control knob so you can turn and select settings smoothly
• Fits onto the control shaft and provides a clear grip for precise adjustments
• Restores proper engagement when the original knob is loose, stripped or broken
• Helps prevent accidental changes by providing a secure press-fit connection

• Disconnect power to the appliance before servicing to reduce risk of shock
• Remove the old knob by pulling straight off the shaft; align splines and press the new knob onto the shaft until fully seated
• If the new knob does not engage, inspect the control shaft for damage and replace the control if needed
• Do not force or hammer the knob onto the shaft; use steady, even pressure
